McCracken announced his resignation and retirement from the firm last Thursday, according to a Deloitte spokeswoman. The resignation came just six days after the Big Four firm made the shock revelation that it was not hiving off Deloitte Consulting (to be known as Braxton).

But the spokeswoman insisted McCracken’s resignation had nothing to do with Deloitte’s decision to hold onto its consulting arm.

Robinson, who was previously global leader of the firm’s public sector practice, has been with the firm for more than 20 years. The chartered accountant’s appointment is subject to confirmation by a vote of Deloitte Consulting partners worldwide.

Robinson said: ‘This is a pivotal moment for Deloitte Consulting. We have many decisions to make in the coming weeks. As we develop our strategy, I am confident the marketplace will continue to recognise Deloitte Consulting as a leader.’
